Funny I had the same thing happen to me this past summer. Was yours a dual-dvi version? Because if it is, they had an issue with them but supposedly not the dvi/vga version. I went through two of them because both of them had ICs that exploded when I ran 3dmark. Chaintech tech support was really nice and but it just took them forever to ship a card back out to me. In the end, for my third card, they just went ahead and bought me a BFG 6600GT to replace their 6600GT. I sold the BFG and got an ATI x800xl instead. So far no problems and I hope in the future Chaintech will test their hardware before shipping them out.
